Hi Bret4, I am an advid water-hunter!! My personal recommendation is if you are only going to hunt in around 1ft. of water, then you can stay with the Sov-GT. But, be VEERY MINDFUL of ROGUE WAVES!! They can RUIN your detector, thus ruinging your day!! If you want to hunt in water ABOVE a FOOT DEEP, then I would personally recommend the MINELAB EXCAL or a FISHER CZ-21, because they are TOTALLY WATERPROOF!! But, before you put out that Extra MONEY for one of them, BE SURE YOU WANT TO WATER-HUNT!! Because you will also have to spend another $100 or more for a Long-handled WATER SCOOP, and I would personally recommend a Stainless Steel Long-handle Scoop for LONGEVITY!! I use both of those detectors, but you will also need an After Market STRAIGHT SHAFT for your MINELAB EXCAL, which will cost you around another $100 or more. With the MINELAB EXCAL, you will be ALOT MORE FAMILIAR
with TONES & NULLS, and that would be a PERSONAL ADVANTAGE over the FISHER CZ-21. Try to find someone with an EXCAL, that you can go water-hunting with, and try it out, before you decide!! BEST OF LUCK, hope this helps, hh, Les Robinson
